Which is the best city to visit? 7d in Hanoi,Danang or Hoian?

A 7-day Vietnam itinerary covering Hanoi, Da Nang, and Hoi An, built around a typhoon-disrupted trip. The route starts in Hanoi with a $50 Airbnb homestay, Pho 10 (Michelin Bib Gourmand), egg and coconut coffee, Ba Dinh Square, One Pillar Pagoda, Train Street, and a Vietnamese BBQ dinner. A flight to Da Nang leads to the Monarque Hotel, where the rooftop pool and breakfast buffet are highlights. Activities include sunrise at My Khe Beach, a visit to Son Tra Peninsula (Lady Buddha statue, monkeys, and coconut coffee at Son Tra Marina Café), Dragon Bridge, and Cham Museum. A day trip to Hoi An covers the lantern-lit Ancient Town, Morning Glory restaurant, and a highly recommended Napoli Italian Restaurant for pizza. The typhoon forced cancellation of a Cham Islands trip, replaced by indoor options: Juno Spa, Grab takeaway, and a coffee workshop at a Go mall. Practical tips include packing a light rain jacket and quick-dry shoes, keeping indoor backups near each stop, and using Grab for last-minute changes.
